How to use the Intex Challenger K1 Kayak
The Intex Challenger K1 Kayak comes with detailed setup and deflation instructions. Fill each valve in the order printed on the kayak itself, and use the included ruler to check each valve for the proper inflation. In warm weather, air will expand, so you may need to release a small amount of air to maintain proper pressure.
YouTubers Van Kookz posted a detailed test and review of the Intex Challenger K1 that you can watch here:

Intex Challenger K1 Kayak Pros
Unlike traditional hardshell kayaks, the Challenger K1 is easy to pack and take anywhere, you won’t need a roof rack for the car, there’s no heavy lifting or complicated storage. It’s a great solution for people who only occasionally want to use a boat for excursions.
Very easy to use
The Challenger K1 is nimble, lightweight, and simple to operate. Setup and deflation are fast and easy, using the kayak is intuitive and responsive, and it’s fun for the whole family.
The rugged vinyl material of the Challenger K1 will withstand minor impacts and abrasions without leaking or puncturing. If it does get a leak though you can use the included repair patch that is very easy to apply.
The Challenger K1 comes with everything you need to start kayaking straight away. You get the kayak itself, seat and backrest, pump, repair patch kit, paddle, and carrying case, so it’s ready to hit the water right out of the box.
Intex Challenger K1 Kayak Cons
The paddle isn’t great
The paddle that comes with the Challenger K1, while being both portable and useful, isn’t the best. If you plan on using this kayak over the long term, for more than just a single summer, you may want to invest in an upgraded paddle.
The seat back may be uncomfortable
Some people find the inflatable seat to not provide enough support for extended trips in the Challenger K1. If you require more support in your back, you may experience some discomfort. However, some people have worked out innovative support solutions using the empty space in the rear of the kayak behind the seat to prop it up and provide a little more support.

Related products you might need
As we’ve said, the K1 comes with everything you need to start kayaking instantly but there are a few additional products to consider to make your kayaking trip a little better.
Life jacket with storage
The Challenger K1 is a pretty small kayak with limited storage options. Since you need a personal flotation device anyway, a great solution is to combine a life vest with storage options. The ONYX Kayak Fishing Life Jacket is great for more than just fishing, with four different pockets, a lash tab, and even a drop down tray pocket to hold items for you. It has adjustable straps and a breathable mesh to dissipate heat.
Upgrade the paddle
While the Challenger K1 comes with a paddle, it isn’t a great one. If you only plan on seasonal or occasional use of the inflatable kayak, the included paddle is perfectly adequate. But if you plan on using it for longer excursions or more frequently, you will probably want to upgrade the paddle.
The Naviskin Kayak Paddles are a bit longer than the included Intex paddle, and are both sturdy and lightweight. They have two piece construction for easy transport and storage. The aluminum body is lightweight for less fatigue over long use, and they have a comfortable grip. They are a great alternative to the paddles that come with the Challenger K1.

- The Intex Challenger K2 Kayak is sporty and fun with a streamlined design for easy paddling
- The bright green color and sporty graphics make the kayak highly visible in the water
- Two 86 inch aluminum paddles and an Intex high output pump for easy inflation and deflation
If you like the look, price and brand of the K1 but you think you might want to take a long a friend, child or just have a bit more room for supplies then you should check out the Intex Challenger K2. It’s almost exactly the same but just bigger, comes with a second seat and second paddle, plus it also has a larger weight capacity so can carry more stuff. It’s only slightly more expensive so it might be worth upgrading if you’re unsure.
Intex Explorer K2

Another option staying with the Intex brand is the Intex Explorer K2. Again, it’s similar in a number of ways to the K1 but has a lot more space being a tandem kayak as well as a lot larger weight capacity as it’s able to hold up to 400lbs, almost double that of the Challenger K1. The only downside is that it all comes at an increased cost but is still very affordable and won’t break the bank.
